Glen W. Cavender (September 19, 1883 – February 9, 1962) was an American film actor.

Glen Cavender was born in Tucson, Arizona, and died in Hollywood, California.

Cavender belonged to the original Keystone Cops and was a regular in numerous Mack Sennett comedies.

During the 1920s, Cavender worked for the film studios Educational and Christie and appeared in Buster Keaton's film classic The General (1926) as the antagonistic Union Captain Anderson.

The advance of sound film in the late 1920s damaged his career and, formerly a well-known actor, Cavender only played minor roles until his retirement in 1949.
